22cb0a76e0 leds-as3645a: Drop fwnode reference on ignored node
If a node is ignored, do not get a reference to it. Fix the bug by moving
fwnode_handle_get() where a reference to an fwnode is saved for clarity.

b1f24498f1 leds: as3645a: Use generic support for composing LED names
Switch to using generic LED support for composing LED class
device name.

After switching to new led_classdev_register_ext() the validity
of struct led_classdev's name property is no longer guaranteed,
and therefore rely on struct device's kobj.name instead.
